Connecting Garmin GPS to D-180

[rvbldr3170]

On my Garmin GPSMap296 there are 2 outputs. One is a a blue wire, and one is a purple wire. The Garmin instructions say to connect the blue wire to a GSD Sounder, and the purple wire to a NMEA device. Is the purple wire the one I should connect to the EFIS input for using information from the Garmin to provide HSI information on the D-180?

Yes, you need just the purple wire, and the ground wire to the aircraft ground somewhere.
